GOP presidential candidate Mitt Romney got a lot of attention on Twitter Tuesday night, but it wasn't because he won the Texas primary and secured the Republican Party's nomination.

Rather, the social media buzz was for a misspelling on "With Mitt," the Romney campaign's new iPhone app that calls for "A Better Amercia." That's right, A-M-E-R-C-I-A -- not America.

The new app allowed users to take a photo and add an image-and-text overlay showing support for Romney, which could then be uploaded to social network sites or emailed to friends and family. The misspelled word was one of 14 overlays, which included (correctly spelled) messages "I'm a Mom for Mitt," "American Greatness," "We're With Mitt," and "Obama Isn't Working."

According to The Washington Post, the Romney campaign has since submitted a corrected version of the app to Apple, which has to approve the update.

As of Wednesday morning, the error was still on the app and #amercia continued to be a trending topic on Twitter. The meme has gone viral, and a dedicated Tumblr page has even been created.

Some of the tweeted jokes included: "Will Mitt Romney apologize for Amercia?"; "I don't believe Mitt Romney was even born in Amercia"; and "AMERCIA TEH BUETIFLU."

"Is our children learning," another tweet read, referencing a past political gaffe by former president George W. Bush.

But as The New York Times wrote, "The typo is unlikely to become a major issue in Mr. Romney's efforts to unseat President Obama. But it is an unfortunate reminder that even the tiniest mistakes are magnified in an era when political opposition is crowdsourced globally. It's also a reminder to double-check your work."

Zac Moffatt, Romney's digital director, told Mashable that the app was meant to be a simple way for Romney backers to show pride in his campaign for the White House. "We thought this would be a fun, easy way to showcase support," Moffatt said.

Though he has yet to publicly address the "Amercia" error, Romney doesn't seem to expect anything to be easy. After winning the Texas primary Tuesday night, the GOP candidate wrote on his website:

"I have no illusions about the difficulties of the task before us. But whatever challenges lie ahead, we will settle for nothing less than getting America back on the path to full employment and prosperity. On November 6, I am confident that we will unite as a country and begin the hard work of fulfilling the American promise and restoring our country to greatness."

And Romney spelled America correctly on his website, in case you were wondering.
